Benefits of technology

The present invention provides a method and an apparatus for securely managing data in a memory database. It involves adjusting the replication factor of data stored in the database based on the memory utilization rate. If the memory utilization rate is high, the replication factor of the data is reduced and data duplicated with the data is deleted. This helps to efficiently utilize the storage space and improve the performance of the database management apparatus.

Problems solved by technology

Such a database has a problem in which a response speed of the database installed on the disk falls with an increase in an amount of data.
However, in the in-memory database, extension of a storage space is not easy as compared to the existing database installed on the disk.
Further, the in-memory database requires a higher cost than the existing database installed on the disk, in the construction of the database.
However, a method capable of effectively managing the data in the in-memory database has not been suggested.

Abstract

Methods and apparatuses for managing data using an in-memory database are provided. One of the methods comprises, determining whether a memory utilization rate is equal to or greater than a threshold value, reducing the value of replication factor of data stored in the memory, when the memory utilization rate is equal to or greater than the threshold value as a result of the determination, and deleting at least one data duplicated with the data, in accordance with the reducing the value of replication factor.

Description

[0001]This application claims priority from Korean Patent Application No. 10-2015-0146033 filed on Oct. 20, 2015 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE PRESENT INVENTION[0002]1. Field of the Present Invention[0003]The present invention relates to a method for managing data using an in-memory database. More particularly, the present invention relates to a method for managing data through an adjustment of a replication factor of data on the in-memory database, and an apparatus thereof.[0004]2. Description of the Related Art[0005]When the database is installed on a disk, a table and an index exist on the disk. Therefore, when a search of a particular material is requested, the specific material first goes through a process of being provided from the database to the memory.[0006]Such a database has a problem in which a response speed of the database installed on the disk falls with an incr...
